Atletico Madrid have arrived at the international break with defeat to Celta Vigo as the team have looked out of sorts ever since victory in the European Super Cup.

These are the reasons why the Rojiblancos are struggling for form.

Over confidence

Since June, the team has been on the receiving end of much praise, particularly for their transfer business of signing Rodri, Thomas Lemar, Antonio Adan, Carlos Arias, Gelson Martins and Nikola Kalinic whilst retaining Antoine Griezmann.

The win over Real Madrid in Tallinn put the side as one of the favourites for the LaLiga Santander, a possibility which now looks more remote than ever as the team have crashed back down to earth with a bump.

Defensive errors

Atletico have always built from a base of defensive strength and reliability, but this season that has vanished as teams have continually threated.

Valencia, Rayo Vallecano and Celta Vigo have all managed to create chances, particularly on the counter, more than Diego Simeone is used to, whilst individual errors are becoming common place too.

Controversial selection decisions

Simeone's latest decisions have been the wrong ones, particularly on Saturday with Stefan Savic at right-back whilst Lemar, Rodri and Arias warmed the bench, with the Colombian in particular frustrated not to make his debut as the only available natural right-back.

The substitutions didn't help either, with Arias introduced for Gimenez, instead of Savic, who had been booked and went on to be sent off, as the team struggled to find any way back into the game, even before the red card.

Lack of threat in front of goal

It remains a work in progress with three games played and two goals scored, a figure which doesn't match with the quality of options in the squad, as, for example, Diego Costa is now 12 league games without a goal.

It is the second worst run of his career as he still hasn't scored in the league this season despite his impressive work rate, but it is goals that count.

Leadership

Two of the leaders in the dressing room have departed in Fernando Torres and Gabi, and they are just as important as any goalscorer.

It has proven difficult to fill their positions since then, particularly when things are not going according to plan, and unity is crucial.

Fitness

It's clear that the team is not feeling fresh, which is no surprising given the reputation of the high demands of a pre-season campaign under Simeone.

Players arrive to the first few games with heavy legs already and it is obvious, whilst Simeone may argue that it ensures the best results in May, it is costing his team early on, particularly after a World Cup and pre-season schedule which took the team around the world.

There are many similarities to last season, when the team eventually got going, but there is much to improve on.
